• The Parking Support Brake deter-
mines that an immediate brake opera-
tion is necessary to avoid a collision.
■The Parking Support Brake func-
tion (static objects) will stop oper-
ating when
The function will stop operating if any of
the following conditions are met:
●Hybrid system output restriction con-
trol
• The Parking Support Brake is dis-
abled.
• The system determines that the colli-
sion has become avoidable with nor-
mal brake operation.
• The static object is no longer approxi-
mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction
of the vehicle.
●Brake control
• The Parking Support Brake is dis-
abled.
• Approximately 2 seconds have
elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed after
the vehicle is stopped by brake con-
trol.
• The static object is no longer approxi-
mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction

■Detection range of the Parking Sup-
port Brake function (static objects)
The detection range of the Parking Sup-
port Brake function (static objects) dif-
fers from the detection range of the
Toyota parking assist-sensor. (P.418)
Therefore, even if the Toyota parking
assist-sensor detects an object and pro-
vides a warning, the Parking Support
Brake function (static objects) may not
start operating.
■Objects that the Parking Support
Brake function (static objects) may
not detect
The sensors may not be able to detect
certain objects, such as the following:
●Pedestrian
●Cotton, snow, and other materials that
are poor reflectors of sonic waves
●Objects which are not perpendicular
to the ground, are not perpendicular to
the traveling direction of the vehicle,
are uneven or are waving
●Low objects
●Thin objects such as wires, fences,
ropes and signposts
●Objects that are extremely close to
the bumper
●Sharply-angled objects
●Tall objects with upper sections pro-
jecting outwards in the direction of
your vehicle

■E-Four (Electronic On-Demand
AWD system)
Automatically switches from front
wheel drive to all-wheel drive
(AWD) according to the driving con-
ditions, helping to ensure reliable
handling and stability. Examples of
conditions where the system will
switch to AWD are when cornering,
going uphill, starting off or acceler-
ating, and when the road surface is
slippery due to snow, rain, etc.

5828-2. Steps to take in an emergency
Stop the vehicle in a safe place
on a hard, flat surface.
 Set the parking brake.
 Shift the shift lever to P.
 Turn off the intrusion sensor and
tilt sensor (if equipped) ( P.79)
 Stop the hybrid system.
 Turn on the emergency flashers.
( P.560)
 For vehicles with power back
door: Turn off the power back
door system. ( P.213)
 Check the degree of the tire
damage.
A tire should only be repaired with
the emergency tire puncture repair
kit if the damage is caused by a nail
or screw passing through the tire
tread.
• Do not remove the nail or screw
from the tire. Removing the
object may widen the opening
and prevent emergency repair
with the repair kit.
• To avoid sealant leakage, move
the vehicle until the area of the
puncture, if known, is positioned
at the top of the tire.
If you have a flat tire
(vehicles without spare
tire)
Your vehicle is not equipped
with a spare tire, but instead is
equipped with an emergency
tire puncture repair kit.
A puncture caused by a nail or
screw passing through the tire
tread can be repaired tempo-
rarily using the emergency tire
puncture repair kit. (The kit
contains a bottle of sealant.
The sealant can be used only
once to temporarily repair one
tire without removing the nail
or screw from the tire.)
Depending on the damage con-
dition of the flat tire, it may not
be able to repaired with the
emergency tire puncture repair
kit. ( P.583)
After temporarily repairing the
tire with the kit, have the tire
repaired or replaced by any
authorized Toyota retailer or
Toyota authorized repairer, or
any reliable repairer.
WARNING
■If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a
flat tire can damage the tire and the wheel beyond repair, which could result in an accident.
Driving with a flat tire may cause a cir- cumferential groove on the side wall.
In such a case, the tire may explode when using a repair kit.
Before repairing the vehicle
